Bits in a hash

WebNov 9, 2024 · SHA-1 is a 160-bit hash. SHA-2 is actually a “family” of hashes and comes in a variety of lengths, the most popular being 256-bit. The variety of SHA-2 hashes can lead to a bit of confusion, as websites and authors express them differently. If you see “SHA-2,” “SHA-256” or “SHA-256 bit,” those names are referring to the same thing. WebThus, the digest has 32 bytes. Since each byte holds 8 bits of information, the hash string represent 256 bits of information in total. For this reason, this algorithm is called SHA-256 and all of its inputs have an output of …
